Initialize the selector with the given Mesh and Topology. This does not create the internal data structures, this happens lazily onGetGeometrySet()
void Initialize ( const [FDynamicMesh3](API\Runtime\GeometryCore\DynamicMesh\FDynamicMesh3) * Mesh, const [FGroupTopology](API\Plugins\DynamicMesh\FGroupTopology) * Topology )
